Their findings, published in the American Journal of Psychiatry, showed that the amygdala and insula -- regions of the brain that contribute to emotion perception, empathy and recognizing when other people are in distress -- were strikingly smaller in teenagers with antisocial behavior.
The changes were present both in those with childhood-onset CD and in adolescence-onset CD, and the greater the severity of the behavior problems, the greater the reduction in the volume of the insula, the scientists said.
Changes in gray matter volume in these areas of the brain could explain why teenagers with conduct disorder have difficulties in recognizing emotions in others," said Graeme Fairchild, who led the research and is now based at Southampton University.
